She told jurors that when she turned to a Muslim cleric for a divorce, he told her that a “white Muslim is not a special Muslim” and she must take her husband back.

She said Aslam should “grow a pair” and come back to Britain and explain himself “if he is innocent and got nothing to hide”.

Aslam’s sister Sarwat told jurors her brother had been in touch with her during the course of the trial to say he wanted to “start a dialogue with police about coming home”.

Shaukat, of Pargeter Street, Walsall, denied helping his friends join IS by dropping Aslam and Nash off at airports.

The convicted burglar and law degree graduate was nicknamed Karma Chameleon during the trial because he presented different versions of himself and his home in the Caldmore area in Walsall is known locally as Karma.

He described IS as “evil” and said that he had told MI5 he would “assist in any way I could” after agents contacted him as treasurer of the community group Islam Walsall.

The former Legal and General personal case manager had several meetings and phone calls with security services before their association “fizzled out”, he said.

Jurors were told about other members of the West Midlands group who allegedly set off for Syria between July and December 2014.

The first to join IS was Muslim convert, Jake Petty, 25, also known as Abu Yaqoob Britany.

His Christian minister mother Sue Boyce wept as she told jurors how she begged him not to go and later had to identify his body from video footage on social media after he was killed in December 2014.

Petty was swiftly followed by former schoolmate Isaiah Siadatan, 24, whose pregnant wife Kerry Thomason, 24, was supposed to fly out with their two children but was stopped by police.

The court heard that he had sent her an email in December 2014 insisting that she should bring their children to him in IS.

Siadatan is believed to have been killed in the summer of 2015, although his death is unconfirmed.

Thomason has previously pleaded guilty to assisting her husband in preparation of his terrorist acts.

Nash, 22, and his pregnant wife Yousma Jan, 20, were arrested by Turkish authorities and sent back to the UK.

He took sole responsibility for the plan and admitted preparing acts of terrorism, while a charge against his wife was discontinued.

The jury was not told about two other men and a woman from Walsall who are also believed to have gone to Syria.

One of the men has since died in fighting, according to unconfirmed reports. The wife of the other man is understood to have given birth to a child after becoming pregnant in Syria.

Neither defendant made any reaction as the guilty verdicts were delivered.

Sentence was adjourned to a date to be fixed.

Judge Charles Wide granted Moore conditional bail out of “concern” for her children.

But he told her she should have “no expectations raised” about the likely sentence. She left the courtroom accompanied by a man who is believed to be a close relative.

Afterwards, West Midlands Police’s Assistant Chief Constable Marcus Beale said the case showed that “whether you are a traveller and going to join” or you are someone who helps in organising, “that’s just as criminal and just as dangerous”.

He said: “Isis (another term for IS) is a really dangerous organisation and the criminal courts will be interested in hearing those cases.”

He added: “Another important part of this case is where you have got people who have knowledge of travel and the intent when they get there who have not come forward, and that’s committing a crime.
